330101-00-11-20-02-CN | Bently Nevada 8 mm Probe 2.0m Cable

Introduction to the 330101-00-11-20-02-CN Bently Nevada 3300 XL Probe

When machinery vibration threatens uptime, the 330101-00-11-20-02-CN from Bently Nevada provides precise measurement. This 3300 XL 8 mm probe uses a 3/8-24 UNF thread and comes without armor. With a 2.0 meter (6.6 feet) total length, it includes a miniature coaxial ClickLoc connector and standard cable. The country-specific approval (CN) ensures compliance for your region. By accurately detecting shaft vibration, this probe helps avoid costly unplanned downtime.

Key Features and Technical Specs

• Linear Range: 2 mm (80 mils) starting at 0.25 mm (10 mils) from target.
• Incremental Scale Factor: 7.87 V/mm (200 mV/mil) ±5% for standard 5 or 1 meter systems.
• Recommended Gap Setting: -9 Vdc, approximately 1.27 mm (50 mils) for radial vibration.
• Probe Tip Material: Polyphenylene sulfide (PPS) for durability.
• Probe Case Material: AISI 303 or 304 stainless steel.
• Operating Temperature: -52°C to +177°C (-62°F to +350°F) for standard probe.
• Pull Strength: 330 N (75 lbf) from patented CableLoc design.
• Nominal Probe DC Resistance: 7.88 ± 0.50 Ω for 2.0 meter length.

The patented TipLoc molding method creates a robust bond between probe tip and body, reducing failure risk. This rugged design lowers replacement costs over time.

Real-World Applications

In rotating machinery such as turbines, compressors, and pumps, the 330101-00-11-20-02-CN monitors shaft vibration and position. Its 2 mm linear range covers typical clearance gaps. For example, in a steam turbine train, this probe provides early warning of bearing wear, preventing catastrophic failure. The 8 mm probe body offers enhanced robustness against physical abuse, extending service life in harsh environments.

Installation and Setup

Mount the probe using the 3/8-24 UNF thread into a suitable mounting hole. Ensure the target surface is clean and within the linear range (0.25 to 2.3 mm from target). Use field wiring of 0.2 to 1.5 mm² (16 to 24 AWG) with a three-conductor shielded triad cable. Maximum field wiring length between the Proximitor sensor and monitor is 305 meters (1,000 feet). For optimal signal integrity, follow the frequency response graphs in the datasheet.

Maintenance and Reliability

Inspect the probe cable and connector periodically for wear or damage. The Viton® O-ring seals differential pressure, but probes are not pressure tested before shipment. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent pressure seal failure. Regular inspection per manufacturer guidelines ensures consistent performance and reduces long-term maintenance costs.

Compatibility and Integration

The 330101-00-11-20-02-CN works with Bently Nevada 3300 XL Proximitor sensors and compatible monitoring systems. The miniature coaxial ClickLoc connector simplifies installation and provides secure connection. For integration into existing vibration monitoring networks, use standard field wiring practices. This probe is designed for radial vibration and position measurement in industrial machinery.
